VTBIREAD FLY.

The rotatable Socket is in two partS 0ne 0f Which carries thewarp-bobbin mounted on a split socket at one end of Which is arrangedthe winding0ff member mounted oh ball or other bearingsand provided withan adjustable brakingdevice.

The other part consists' of a'socket rotating as usual round the hollowshaft and engaging with sl ight friction in the splic Socket of theother part the Walls of Which it forc es apart So that they pressagainst the i1111er Wall of the warp-bobbin;

This; 'method of mounting has the advantage of facilitating thexehangeofjthe warp-bobbin by a simple disconn"ectionf the members wv1t-houtnecess 1tatmg the use of screws f0r re-a's'sembhng the parts- (11S-mounted forbo1 bin Changing OIJBI'MOIL Difierent forms 0f eonstructionof the movable. ber can be arranged; in particular; it canbt providedwith a single hole through which Passes the teXtile 01' 0ther c0re whichthe spun thread isto cover or With a hole of 1:11g01 size aifordingpassag'e t0 2mextensio:n 0f the hollmv shaft'vvhic1rtlms protects (1]1esaid eure frorn any contact with tl1e 1'0- tnting pmt of the fly.

The annexed chrawing illustrates, two forma 0f construction 0f th einvention.

all citizens 0f th ed f0r instance, by

pa'rt carrying the winding oflmemy illustre th@ c n i fi Fig. 4'is' alongitudinal sectioh of zu modification i11 which the .hollw' shaftextends -gompletely through the 1cotating pzuft of 'The warp-bobbin a ismounted 011 a split socket b (Fig. 2) 011 the one side of which thewinding ofl member c is suitably mou'nta ball bea1ing d which reducesthe friction. Braking 0f the member c 02111 be effected either b vmean's of a spr1ng the tension of which is adju3table. or-by means 0f aleather washer e the pres sure of Which a'gainst the bearing .case f canbe regulafed by means of fl1e nut g and locking'nut h. v

The other -part of the fly (Fig. 3) comprises the hollow shaft z Whichis terminated by a cylindrical bearing whifch abuts the sleeve ksupported 0n the head j z'mgainst other side by the adj stable bea1ingorcol lar Z which is slidable 011 the shaft z and i.s fixed by ineans ofthe screw m.

The sleeve k which serves as a bearing memberis provided with anoil-ehamber 41 Which can be filled through the orifice 0 provided with aspring cap p.

The warp-bobbin a being slid 011 the split socket Z) is se0ured theretoby the introduc tion into the interior 01 the latter, 01 the sleeve kca,rried by the hollow shaft z.

The gentle force used opens t-he halves Q 0f the split socket Z) theWalls of Which are thus firmly pressed against those' of the warpbobbiha.

the :rotating part s prevents the mountingofthe winding 01T member 0 011a ball bearin'g of the usua] type, ba1ls 25 being inserted between thewinder-n'ff holdingdisc u and the Chek v or the washer w The Wh0le isThe increase 0f diam'eter oif' kept connected by tightening the nut gand lock-nut h, between which is a paoking washer e.

In this manner the c0re f01 ehe thread which asses through the hollowshaft i is surrounded by said shaft und protected until itissuesfro1nthe tube m.

Vhat we claim as 0u1 invention and desi1'e t0 secu1e by Letters Patentof *the United States is:

1. A thread fly comprising a split socket a rota1y member mounte d ab0ne end of said socket, thread guides canied by said rotary 1nember, ahollow shaft a sleeve 1'0- tatably mounted on said shaft and engaged byfriction in said split Socket and a warpbobbin mounted on said sp1'1tsocket.

2. A threacl fly comprising a split socket a member-having a centralorifice mounted atone end o:f said sooket, a b2111 bea1ing Carried bysaid member a rotary member mounted 011 Said ba1l bearing thread guidescarried by saicl rotary 1nember a hol1ow shaft a head at one en l ofsaid shai't a bearing 1nember keyed oh sa'1d shaft, a s1eeve rc' tatableabout su'1d head shaft and bearing member Said sleeve engaging in saidsplit socket by friction a warp bobbin mounted on said split socket and1neans f01 lub1icating said rotatable s1eeve.

In witness whereof WG hzwe signed. this specification in the presence oftwo wit nesses.
